Held : 24th – 28th September, Peine, Germany
Course Outline
This five-day course concerns all of the key aspects of geological disposal of radioactive wastes in sedimentary environments, including evaporites. It covers the scientific and technical background of the hydrogeology and hydrochemistry of sedimentary environments, the engineering properties of clays and evaporites, the design of repositories and site characterization in sedimentary formations. Safety assessment is also covered in detail, through a series of six case studies in different sedimentary and evaporite environments.
A particular feature of this course is an in-depth look at the practical aspects of managing both a planned and an operating repository – the Konrad and the Morsleben facilities. Field visits will be made to the surface and underground works at both sites and there will be detailed lectures on site characterization, safety assessment and the issues involved in closing a repository at the end of its operational life.
The course is ideal for those involved in any component of a national waste programme that is considering repository development in sedimentary formations.
Course Organiser
The course is organised by the ITC-School in collaboration with, and supported by, the IAEA (International Atomic Energy Agency) within its network on Training and Demonstration of Waste Disposal Technologies in Underground Research Facilities (http://www-tc.iaea.org/tcweb/default.asp).
The local host organisation is DBE Technology in whose offices in Peine the course will be held and who will guide the field visits (http://www.dbetec.de/en/about-dbe-tec/the-company/).
Teaching
The course will be held in an informal, workshop atmosphere and participants will be encouraged to interact and question at all times. Each course topic will be taught by highly qualified and internationally recognised specialists from a range of organisations active in the field of radioactive waste disposal. They will provide the most up to date and comprehensive information and discussions. Course materials will be provided for each topic. The course language is English and course materials are printed in English.
